Government-owned China National Nuclear Corporation (SinoU) is facing worker protest at its uranium mine Somina in northern Niger.

The Syntramines labor union stated that 680 workers had proceeded on a 72-hours strike demanding better wages and bonuses, reported PressTV.

Syntramines labor union spokesperson Boubacar Mamane stated, "Management refused to pay our allowances and production bonus despite having promised to do so last year. If nothing is done, we will launch an unlimited strike."

The Nigerian government owns 33% stake in the Somina mine and it has an annual production rate of 700 tonnes.

SinoU and its partners are however keen to increasing the annual production rate to 2,500 tonnes by 2015.
